I've been thinking that what Staticmatic needs to drive it's popularity is
to be a turnkey blogging platform out of the box (or in as few steps as
possible.) I'm all in favor of using free services that people have already
made so here's my plan:

-Posts

Staticmatic already has good support for posts, because posts are just
websites. To make posts you just write content and have it rendered by
Staticmatic. Easy enough.

-Comments

A good embeddable comment site is Disqus (www.disqus.com), it does nearly
everything I could want in a comment engine.

-RSS (the hard part)

I haven't found a good service for building RSS feeds from a website yet. If
anyone knows a good service I'd like to use it to save work. My plan right
now is to integrate RSS generating functionality directly into Staticmatic.

To make a directory have RSS support, you would put an atom.xml.haml file in
the directory you want to enable support for. Then inside that file there
would be ruby expressions that 1. build a list of files and publication
dates and 2. takes this list and outputs an RSS feed in Atom format. If the
publication date is left out, we'd use the file modification time.

This RSS code would also include some code for generating an archives page.

I'd want to make this as easy as possible to use, so that might involve some
custom rake tasks for writing new posts. Any suggestions about how to make
this simpler would be welcome.

Also, please let me know if you think there are some fundamentals to blogs
that I haven't addressed.
